Functions- Intro

Functions are reusable blocks of code that group together sequences of statements to perform a specific task. In computer programming, we want to avoid writing the same block of code multiple times if it can be avoided. It is much easier to reuse a block of code the next time we need to perform the same task. Over the next few lessons, we will be learning about JavaScript functions and how they can make our code concise.
